Abstract

Claims (12)

1. A flow rate assembly comprising:

a housing having:

a housing axis;

a first end having an inlet positioned along the housing axis;

a second end having an outlet positioned along the housing axis; and

a measurement channel extending along the housing axis and through a portion of the housing between the first and second ends of the housing, the measurement channel having a width perpendicular to the housing axis;

a first sensor assembly positioned at least partly within the housing, the first sensor assembly comprising a first transducer positioned along the housing axis, the first transducer having a width perpendicular to the housing axis and greater than the width of the measurement channel, the first transducer configured to generate an ultrasonic signal and to direct the ultrasonic signal through the measurement channel; and

a second sensor assembly positioned at least partially within the housing, the second sensor assembly comprising a second transducer positioned along the housing axis, the second transducer having a width perpendicular to the housing axis and greater than the width of the measurement channel;

wherein the second transducer is configured generate an ultrasonic signal and to direct the ultrasonic signal through the measurement channel toward the first transducer, the flow rate assembly further comprising a housing interior chamber within which at least one electrical component is positioned; and

wherein the housing interior chamber has no holes and no electrical lines which communicate with the measurement channel of the housing and the first and second ends of the housing are configured to mate with an open pipe end in an in-line manner.
